  • Publication number: 20070202483
    Abstract: A method and system for computer-assisted analyses of best practice safety assessment generates quantitative indicators of safety performance by using a questionnaire with questions in various sections directed to different areas of safety performance evaluation. Scores are given to the questions based on answers entered by an evaluator. The scores for the questions in each section are weighted and summed to provide a section score, and the section scores are weighted and summed to generate an overall score for the assessment. The scores for the individual sections and the overall score can be compared with scores of other clients and the average scores of the industry, and expected losses can be predicted based on the scores.

  • Patent number: 6407562
    Abstract: A probe tip adapter with easily interchangeable termination. It includes an empty circuit substrate with which the user may construct a probe adapter circuit designed specifically for almost any measurement situation. Also, several standard termination circuits may be easily interchanged by the user to allow the same probe tip adapter to work with transmission lines of different impedance.

  • Patent number: 6094042
    Abstract: A probe tip for connecting an instrument to a circuit under test is disclosed. The probe tip is interchangeable with other probe tips to provide different attenuations of the signal under test to the instrument. The signal from the circuit under test is coupled to the instrument via a cable. The probe tips have a compensation network that cancels the effects of cable loss. The probe tips provide attenuation by using the probe tips internal impedance, and the characteristic impedance of the cable, to form a voltage divider.
